NOVELTY - Sulfur-doped graphene catalytic material comprises 0.2-0.85 wt.% graphite powder, 0.3-0.6 wt.% sodium nitrate, 1.5-2.6 wt.% potassium permanganate, 14-18.5 wt.% concentrated sulfuric acid, 0.01-0.07 wt.% persulfate, 24-30 wt.% hydrogen peroxide and water (balance amount), where the sulfur atoms are supported in a single form of edge loading on a graphene structure composed of a six-membered carbon ring. USE - Used as sulfur-doped graphene catalytic material. ADVANTAGE - The sulfur-doped graphene catalytic material: has low cost, and is suitable for scientific research and industrial production. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for preparing sulfur-doped graphene catalytic material, comprising (i) mixing concentrated sulfuric acid, graphite powder, sodium nitrate and aqueous solution, then placing in an ice bath at 0-55 degrees C, mixing and dissolving, adding potassium permanganate and reacting at a constant temperature for 0.5-2 hours to obtain mixed solution, (ii) placing above mixed solution in an oil bath at 90-100 degrees C and reacting at a constant temperature for 0.5-1 hours, then adding hydrogen peroxide to remove residual oxidizing agent, and (iv) stirring material obtained in step (iii) at room temperature, adding persulfate, mixing, sealing in an autoclave reactor for reaction and reacting at 90-130 degrees C for 1.3-6.2 hours to obtain sulfur-doped graphene catalytic material.
